    the common function output_move_memory.

    and one for everything else, so that the combiner will combine a
    load with a store into a memory->memory move.
    (untyped_call): Replace non-working code with m68k version that

    flag_cse_follow_jumps and not leaf_function_p to determine whether
    to allocate EDX, and ECX before EAX, use whether or not a DImode
    variable was used in the compilation.  DImode variables seem to
    cause spill failures if EAX is allocated first, while smaller code
    is generated if EAX is allocated first, assuming no spill failure.

    * i386/i386.md (SF, DF, XF, and DI moves and pushes): Eliminate
    special patterns for TARGET_386 that allow direct pushes from

    (addsi3): Allow generation of lea on 486, since the single
    instruction lea is at least as fast as the mov and add it
    replaces.

    * i386/osfrose.h (LONG_DOUBLE_TYPE_SIZE): Don't redefine to be 64

    as permitted by ANSI C.

    * getpwd.c (GUESSPATHLEN): If there is no definition of
    MAXPATHLEN, then set GUESSPATHLEN to be 100.  (It's used

    * i386/i386.md (movxf_mem): Fix typo with memory/memory moves

    source and destination operands were fixed.

    (movdf_push486, movxf_push486, movdi_push486): If an address is
    based on the stack pointer, account for the stack pointer changing
    due to the intermediate pushes generated.

    switch to allow users to override the register allocation order.
    (OVERRIDE_OPTIONS): Call the function override_options.
    (REG_ALLOC_ORDER): Define to allocate in the natural order, this
    is needed for ORDER_REGS_FOR_LOCAL_ALLOC to work.
    (ORDER_REGS_FOR_LOCAL_ALLOC): Define to call the function
    order_regs_for_local_alloc.
    (regclass_map): Move declaration to end of file.
    (i386_compare_op0, i386_compare_op1): Ditto.
    (CLASS_LIKELY_SPILLED_P): Define, return 1 for AD_REGS in addition

    registers in the normal register order.  If -mreg-alloc=<xxx> was
    not used, allocate registers in natural order except for non-leaf
    functions with CSE following jumps, allocate EAX after EDX and
    ECX, to allow the function return to be CSE'd, and perl 4.036's
    perly.y to be compiled without aborting due to not being able to
    find a spill register.
    (movsf, movdf, movdi): Rewrite all patterns to provide effecient

    (swapsf): Add, like swapdf and swapxf.
    (fixuns_truncsfsi2, fixuns_truncdfsi2): Use general_operand
    instead of register_operand for define_expand, since the operand
    is copied to a new pseudo register as part of the expansion.
    (fix_truncxfdi2, fix_truncdfdi2, fix_truncsfdi2): Rewrite to call
    the more primitive generator functions instead of knowing how many
    clobbers of match_scratchs they do.

    * Makefile.in (aux_output.o): Define TARGET_CPU_DEFAULT if
    specified when compiling aux_output.o to allow the machine C file
    access to this if it wants it.

    factor, swap with the base register.

    * i386/i386.h (REG_CLASS_CONTENTS): Don't allow the arg pointer

    here from i386.h.  Combine OSF/rose support from osfrose.h through

    memory insns to be generated unless -mno-move.
    (movdi): For movdi patterns, add 2 (clobber (match_scratch...))
    declarations to allow memory<->memory moves with non-contigous
    registers, so that reload don't abort if it can't make a DI
    register.
    (umulsidi3, mulsidi3): Don't allow pattern if -mno-wide-multiply.
    (smultsi3_highpart, umultsi3_highpart): Add patterns to make
    division by constants generate better code.

    for compatibility with i386.h.
    (NO_IMPLICIT_EXTERN_C): Define.

    just #undef'ing it.
    (GO_IF_LEGITIMATE_ADDRESS): Delete, merged with common i386 code.
    (ASM_FILE_END): Print -fschedule-insns and -fschedule-insns2 in

    as part of configuration setup.  Also, manually include cc1plus

    extension to some lists of object files passed to the linker;
    general cleanup of the command text echoed during execution.
